TERAZZO FLOORING.

A Application filed August 3Q, 41922. Serial No. 585,1'96.

To all whomz't may concern:

Be it known that I, Louis VINoEN'i1 Fospanels or sections, as shown in Fig. 2, for mstance. Usuallythe strips are laid straight and the panels are rectangular in form. The

America, residingin Bayside, in thecounty \strip D best comprises a narrow sheet of of Queens and State of New York, have invented certain new and useful Improvements in Tera'zzo Flooring, of which the following is a specification. y

This invention relates flooring, particularly, of what is knownv as lthe terazzo types, that is to say, flooring which comprises a foundation bed usually -of cement, and a superposed layer'composed of small pieces of marble united together with a suitable bond. In laying such floorings, it is well understood that the underlyv pose of ocalizing any possible cracking of lhe terazzo, and also for the purpose of introducing pleasing designs into the flooring. Such strips have heretofore been constructed so that their top edges constitute a` levellingl gauge, so as to'facilitate the laymg of the terazzo body.

My invention includes a novel form of strip which can be very easily and cheaply manufactured.

In the drawings, wherein I have illustrated one form of the invention,

Figure 1 is a cross-section of the flooring made according to the present invention.

Fig. 2 may be regarded as a plan of Fig. 1.

Fig. 3 illustrates the construction and operation of the means for Aembedding or.in-

length and shape to divide the flooring into to, composition Brass having at suitable intervals triangular projections E struck outwardly from the body of the metal, it being' preferred to arrange these projections in pairs, and to extend adjacent pairs from opposite sides of the' strip. When the projectionsare bent outward1y,they referably extend at right angles to the bo y ofthe strip, and their upper edges are straight, or in other Words, perpendicular to the side of the strip. Their lower edges are bevelled or inclined, joining the strip near the vlower edge of the latter. This construction enables the strip to be inserted .in the cement foundation with the least disturbance of the latter and with the greatest amount of facility. It Will be understood that the strips are not inserted until the cement has become somewhat set, and therefore, resists the embedding, of the strips to a considerable degree.

The upper edges F of the projections E constitute levellmg means, so that if the strip is inserted to a point where the edges F are at the same level with the upper surface of the concrete foundation, the operator is assured that the strip has penetrated to the right degree, and that the upper edge F of the entire strip is level. The cutting of the projections from the body of the metal leaves apertures H H triangular in shape, into which they concreteiows, thus forming a bond or anchor, tending to preserve the strips in their initial position, whichvtendsov ency becomes positive When y"the concrete has become hard. v

In laying such strips, I make use of the device shown in Fig. 3, which comprises a strip of wood or other suitable material J, having secured to its upper face and one side face anA angle-iron K, the vertical side L of the angle iron being spaced apart from the strip J a sucient distance to insert the top of the strip D. Preferably a lining strip M is also provided, so that in use the laying device is not materially aected by wear. Preferably between :the lining strip M and the side L of the angle-iron I introduce a strip N, the lower Side of which not only provides a means for spacing the side L and strip M apart, so that the space thus formed snugly receives the upper edge of the strip D, but also serves as an abutment for limiting the insertion of the strip D in the member K. Preferably the side L of the angleiron is of just sulicient depth, so that when the top edge of the strip D contacts with the spacing strip N, the lower edge oit the angle-iron will contact with the edges l? of the projections E on one side of the strip D, while the lower edge of the liningmember M will contact with those on the opposite side of the strip D` ln actual application the laying member K is fitted. over the top of the strip, and the lower part of the strip Dressed into the bed or concrete until the' bottom edge t) of the laying member lies flat upon the upper surface of the concrete. rllhis usually requires considerable torce, as bv the use or a hammer. Preferably the lower surface 0 ot the member K is of more extended area than the top, so as to provide a stop of considerable surface area which upon contactin^ with the upper surface of the concrete will tend to limit anjv further downward movement of the strip. llVhen the proper position is reached, the member K is removed, leaving the strip D embedded in the concrete,` the member K being then used for the succeeding strips lr there has been any error on the part of the workman in failing to sink the strip D suticiently, the upper edges lll of the projections E torni an accurate gauge for further depression.

renace-s l/Vhile l have shown and described several forms oit the invention, it will be understood that ll do not wish to be limited thereto, ,l
